Où finit l’analyse de l’expert et où commence l’appréciation du juge lors d’une expertise ADN en matière pénale ? Analyse critique d’un cas concret

Abstract

Forensic expertise, specifically DNA identification, is increasingly being sought in criminal trials. It is well established that genetic expertise is an essential tool available to the justice system to provide a criminal response. This is so only if it is exploited by the legal framework governing its administration as criminal evidence. The latter provides that, although the analysis and interpretation of the scientific result are reserved for the expert part, it is nevertheless to the court to assess that part. While in theory, the boundaries drawn by the legislator appear clear, the practice reflects a confusion of role, thus calling into question the very essence of expertise.
